GEORGE W.'START, OF IORTLAND, OREGON, ASSIG'NOR`OF ONE-HALF TO GEORG-E KI1\T1\T'IE}.ABY OF PORTLAND, OREGON. v

oIL BURNER.

Application filed May'23,-1925. SeralkNo. 32,351.

To .all whom t may concern:

Be it known that I, .GEORGE IV. START, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

My invention relates to certain new and useful improvements in oil burners of the type adapted to the use of crude oil'fuel,y

Vand it is the object of this inventionv to provide a burner of a simple and effective construction which may be used without motors and pumps, which willy not readily clog, and Y which, 'should it become clogged, may be readily cleaned without dissembling the' structure andA without Vthe use of special tools or cleaning implements.

The invention resides .in those novel features of construction, combination and arrangement of parts, which will hereinf after be described, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawing, in which:

Figure 1 is a longitudinal section of a burner constructed in keeping with my invention. v

Figure 2 is a detail 'frontelevation of the nozzle. n

In the drawing, in which like numerals of reference designate like parts in all the figures, 1 is the pipe line from the oil reservoir or tank (not shown). 2 is the oil throttle valve, 3 the combined steam and oil throttle valve and 4 the steam jacket pipe connecting the valves 2 and 3.

5 is the oil feed duct located within the pipe 4.-, one end of the duct 5 being welded to the pipe to form a cutoff therein, while the other end is left open as shown.

6 is the steam inlet connection to the pipe Ll, and 7 is the throttle valve which .controls the admission of the steam to the inlet 6.

8 designates a T which is connectedby a pipe 9 with the valve 3 and to which is connected the duct 10 through which the combined vaporized oil and steam are passed to the nozzle o r burner tip.

12 is the steamoutlet of the nozzle 11 and 13 is an oil baie thereof which delivers the vaporized oil and steam issuing from the nozzle down across the path of the ejectorsteam issuing from the outlet 12 of the nozzle. Themixture'of vaporized oil and ,steam passes out of the opening 14 of the nozzle 11.

` 16 is a steam control throttle valve kthrough which steam flows to an auxiliary steam duct 15 that is located within ther burner which is preferably located below the fire box of the furnace. n I/Vhen steam is admitted-through the valvef and after the valves 2 and 3 are opened the steam will pass around the pipe 5, through,` valve 8, T8, pipe 10 tothe outer Vchamber 17 of the nozzle or tip 11 and out through the opening y14. As the steam passes the forward or free end yof the pipe 5 it creates a partial vacuum or .suction there and draws oil fromthe tank through the pipe line 1 and valve 2 into the pipe 5 from which it issues and is mixed with the steam before en tering the valve 3, thereby atomizing the oiland mixing it with a quantity of the steam.

This atomized mixture then passes throughk therefrom, thereby preventing Vcondensation as the mixture passes through the pipe 10. As the mixture of atomized oil and steam passes out of the nozzle 11 it travels down in front of the port 12 where it encounters the ejected steam from the inner chamber 18 of the nozzle and is there further atomized and ejected into the combustion chamber of the furnace. Thus it will be seen that by my construction the oil undergoes av primary breaking up (atomization) on leaving pipe 5 and Ventering valve 3, and a final or auxiliary breaking up or atomization as it leaves the nozzle 11 and encounters t-he ejector-steam jet issuing from the port 12. Thus the oil is thoroughly atomized and mixed with the steam vapors before entering the fire box and a more perfect combustion (consequently vless production of smoke) is had thanwith other burners such as are in common use.

Should it be found desirable to clean the burner, if'it be clogged forwardly, i. e. in the tip or nozzle end, it is only necessary to close the valve 2 and open the valves 3 and 7, whereupon the steam will scavenge the burner thoroughly, blowing out the dehrie through the opening,T lil; it the oil line be clogged it is only necessary to close the valve and open the valves 2 and't-` to canse the steam to force the contents hack into the tank troni whence it cante.

Should the oil get thick as in eold weather, it can he heated in the tank and the pipe line heated Simply hy closing the yalve 8 and opening. valves 2 and 7, blowing haelt the oil in the pipe and adn'iitting,r steain in to the pipe line and oil tank.

The advantages ot` niy invention, it will he seen, reside principally in the (facts that (l), there ie a eating; of installation coste over those systems using; motore or pumpe; the burner muy he readily cleaned withw out being; Shut doiin and taken apart; and (3) a breaking up and etoinizing ot oil on entering valve which continues onto the `tip and is treated toav second atoniimtion atthe place ot trein the `tip eene-ing a supply ot oxygen to hc mixed irith the oil at the place where the steam .tiret niixee With it and an additional Supply ae the mixture leaves the burner tip, thus rcseltingin )racticelly portee-t eonilmetion in the coinustion chamber.

From the vtoregeilt@ description, taken in connection with the` accoinpmiying drawing, it is thought the construction, operation and advantages ot niy invention will he clear to those skilled in the art to which it eppertains.

What I claim ist:

In crude oil burners, an oil line, an oilthrottle valve to which the saine leads, a second throttle "valve, e j acliet pipe connecting said throttle valves, en oil feed pipe located within said jacket pipe and secured at one end Within the same to torni en annnlar chamber and to receive the oil 'from seid oil throttle valve and deliver it into said jachetpipe at a place reniote troni said oil throttle valve, a eteani inlet dnct with a priA mary steam vulve tor deliroring` steeni into Seid jacket pipe at a place adj acont Said oil throttle Valve, Wherohy the oil and Stettin will )nix on entering said second throttle ialve, a burner nozzle, a pipe connectingi said :second throttle rnlve with seid nozzle to deliver the mixture thereto, and nieanel tor delivering;1 and ejeetiiig etree-nie ot steam troni said nozzle to engage the niiiitnre ae it issues vtroni the nozzle and further repen ize the oil and deliver the mixture to the place i'or combustion.
